SOLVED! Post 2853 Leaking Injectors, Dealer Techs Rock! Extended Cranking after Engine Swap 3.4L 5vz

Pic upload test. Liking it.
From a few days ago, a new Dino Track site. The 2 acres of slickrock in the foreground contain over 2300 tracks.

 

also the taco has a steady return to its peak while the 4runner has more of a wave action "float" to it

 

Tacoma wave form looks more uniform/better to me.

 

would the amount of gas in each tank make a difference in the test results?

 

As far as the fuel pump on/off goes. The ECM needs to see engine rotation signal (NE) from the crank sensor to allow "pump run". During starting an additional signal from the starter relay (STA) "adjusts fuel delivery during starting". It's 9v or better on terminal something or other on the ECM, we discussed this way back and I think "good neighbor tech" (with the death in family) checked it.

ALERTS! what the heck is that?
Never mind, got it. This is like a new car.

 

hmmm,,upgrades. I like the draft saved thing,,lost to many to innerspace/dumbthumbs. This color is asanine bright tho'.

My saved sigs are still there (thank you). Guess I need a avapic versus the simian symbol.

 

Liked that pic you posted DP! Beautiful!! In fact, we may have to move there. Koditten, plans changed, everyone is moving to DP's neighborhood. Hetkind will bring the whiskey barrels....

DP, I remember you posted some awesome Obsidian pics a while back. Here's pics of our hike through Obsidian country in central OR. And Patty & Dolly's matching stride, competing for the lead : )

 

Yeah, get a pic man!!

The draft save thing is cool, definitely. Lost more than one myself to hitting some key by mistake......

East bound and down, loaded up and truckin',
we're gonna do what they say can't be done.
We've got a hot start to fix and it's a PITA to get there.
I'm east bound, just watch ol' "Taco" run.

Keep your foot hard on the pedal. Jay, never mind them brakes.
Let it all hang out 'cause we got a run to make.
Keakar's making moonshine in Louisiana and there's whiskey at Hetkind's.
And we'll bring it back no matter what it takes.

Ol' Noahpete's got them ears on and he's hot on your trail.
He aint gonna rest 'til them damn hot starts are in jail.
So you got to dodge 'im and you got to duck 'im,
you got to keep that Taco truckin'.
Just put that hammer down and give it hell.

the words fit perfect

OK, all mechanics, be honest - is this what really goes on when you test drive cars?

EDIT: If so, I really need to get my butt in school to work for Toyota! That would be some serious fun : )

what are engine expansion plugs? I noticed a couple of new shiny things on our remanufactured engine. what purpose do/did they serve?

 

Are these freeze plugs on the engine block? If yes, they are there to pop out if someone does not use antifreeze. If straight water freezes, it expands and pops these out vs cracking the block.

 

That's the hope anyways. They don't always work as well as advertised. They can still pop out and the freeze can still crack the block. Little round disks of wishful thinking. Sometimes the freeze can press/dent right on the center of the disk inside,,and roll lock the outside edges to the block so it can't move and pop free.

Just always have good Antifreeze loaded.

Post #4 on this link, the guy says his dad's truck had excessive cranking after 3.4 swap, and it wound up being the igniter. We tried Koditten's igniter already, but I don't know if the Taco was driven with the donor in it at all, or if was just started a few times with the donor in. Would that matter?

And this guy started getting excessive cranking problems on his 5vz after changing his fuel filter........

I am still bothered by the leakdown test results...I found this link:

http://www.wcengineering.com/articles/leakdown.html

But I think this sentence is important...A freshly rebuilt engine should have less that 4% leak down on each cylinder and if leak down is above 10%, service should be performed. All cylinders should be within 2 percentage points of each other. NOTE: These figures are for performance engines. Stock production engines may have as much as 10% right off the assembly line.

And we saw numbers up to 30%. I think we have valves that are sticking slightly open when warm.

I know this is the wrong year, and wrong engine, but I found this FSB that addressed hard starts. The short version is there is no injector pulse on the first crank, then the second crank the vehicle starts. I believe the fix they are offering is to flash the ECM with updated software, and make sure to label under the hood of the vehicle. I wonder what the firmware update is actually doing/telling the computer?
